Title: Method for the crosslinking of polymeric materials
IPC: C08K3/00
Filed: 1963-08-22
Abstract: A thermoplastic resinous composition comprises a copolymer of a monoethylenically unsaturated monomer and a free carboxylic acid group-containing monomer, and from 2 to 90%. by weight based on the composition of a hydrolysable co-crystallized oxide of a base-forming metal and an amphoteric element, the copolymer containing from 0.2 to 25 mole per cent of the carboxylic acid group-containing monomer. The co-crystallized oxide is a compound that contains as a whole no free oxide of either of its components, which components have been crystallized together to form a salt-like hydrolysable compound. Many suitable copolymers are specified, those exemplified are: copolymers of ethylene with methacrylic acid, maleic anhydride, maleic acid, methyl hydrogen maleate, fumaric acid, and itaconic acid; the copolymers methyl methacrylate/methacrylic acid, styrene/methacrylic acid, and vinyl chloride/methacrylic acid; the tercopolymer ethylene/vinyl acetate/methacrylic acid; and the graft copolymers of methacrylic acid grafted on polypropylene and of methacrylic acid grafted on an ethylene/butene copolymer.  The preferred co-crystallized oxide is Portland cement (which is ideally tricalcium silicate), others exemplified are MgO/SiO2, MgO/SiO2Al2O3, 2.4CaO/Al2O3 and NaO/3.5 SiO2; also mentioned are Sb2O3/CaO, SnO2/CaO, PbO2/CaO and TiO2/CaO.  The composition may include the usual additives such as pigments, stabilizers, antioxidants and plasticizers.  In one example carbon black is incorporated in the composition.  Cross-linking of the composition is effected by aquasetting, i.e. by treating the composition, after shaping or forming into an article, with water.  Boiling water is preferred, but water at higher or lower temperatures may be used.  In the examples the composition is formed into sheets which are aquaset by immersion in boiling water or by treatment with water under pressure in an autoclave, and it is also extrusion coated on to wire and aquaset with boiling water.
